otherwise suitably joined Fig. 5,'i`s an enlarged sectionalviewlof the joint," between the roof modified formof outer l orframe members f cavitieszl. Thus of` the car ori-container together and to the upturned floor portions I8. The roofing 21 for this inner shell is formed by similar plates or sheathing which is riveted or otherwise suitably joined to the side and end walls. This inner shell is reinforced at spaced intervals by angleiron frame members 28 secured to the outer side of said sheathing and extending up the sides and over the roof and also upwardly at theends of said shell as shown in Figs. 1 and 3.

The inner side of the corners of the inner shel1 are also reinforced by the angle iron frame members 29.

The outer structure or shell is, with the exception of the corners and door openings, free of any connection with the inner shell. The ksides and ends of this outer shell are formedy in each instance of a plurality of metal plates 30 lwhich are suitably joined together and connected to the frame of the car, these plates being so connected that they may be readily removed entirely from the outside of the car and without disturbing`l yany of the inside wall structure of the car.

Preferably the sides of the plates 30 have flanges 3| secured by rivets 32 or other suitable fastening means to the frame members 33 of T-bar form shown in Fig. 3 or the frame member 34 of angle form shown in Fig. '1 or the frame member 35 of channel form shown in Fig. 8, in each instance it being ioted that the flanged connections thus provided between said plates and frame members permit disconnection of the sides of the plates from the outside. As a further modication, the plates 30 may have their side flanges 3| directly riveted or otherwise suitably directly connected together as shown in Fig. 9. Y

' At the door openings 35, frame members 31 of wood or other suitable insulating material are disposedbetween the plates forming the inner and outer shells, said members being reinforced by angle iron frame members 38 secured thereto and also connected to the adjacent wall plates.

At the corners, frame members of wood or other suitable insulating material are disposed between the plates forming the inner and outer shells, said members being reinforced by angle iron frame members 40 secured thereto and also connected to the adjacent wall plates.

It is to be noted that the angle iron frame members 38 as well as the frame members 40 are in each instance spaced from each other so that no metal conducting path is provided between the outer and inner side walls of the structure thus far described, though a'suboor metal channel member 4| is disposed between said walls and supported upon the'ribs I6 and a lengthwise extending channel beam 42 secured to the end portions of said ribs or beams I5, said subfloor however, preferably being out of direct contact with the plates forming the outerl wall. This subfloor channel member 4| may have openings to permit the drainage of'any moisture from the space between the inner and outer walls.

For reinforcing the side and end walls at the corners I have provided in each instance, and as best shown in Fig. 3, a T-bar 43 whose base flange portion 44 is secured to the'side wall plate that extends to the corner and whose base flange portion45 is secured to the flange 3| of the end wall plate 30, a reinforcing T-bar 46 being also secured to said plates by the same rivets 41 and 48 which respectively secure the T-bar 43 to the side and end wall plates above mentioned. y

The outer shell structure is also preferably reinforced adjacent the door openings and at the corners by diagonally extending angle iron brace bars 49.

The plates forming the sides and end walls of the outer shell have outwardly extending end flanges 50 to which an angle iron frame member 5| is secured, which member extends around the entire car and forms a support and connection for the roof structure. Where the T-bars 33 are used, a portion of the web is cut away adjacent the upper end 52 of each bar, so that one side of the angle frame member 5| abuts against and.

is secured to this end as by rivets 52'.

The roof is formed by a plurality of metal plates 53 extending from the sides to the center, said plates having their adjacent sides connected to gether, their upper ends also connected together and their lower ends connected to the frame or rail 5|. Each plate 53 has side flanges 54and end flanges 55 and 56. The side joints are formed as shown in detail in Fig. 6 wherein the side flanges 54 are shown abutting oppositely disposed arched angle iron frame bars 51 which extend from one side of 1the roof to the other and whose lower ends are secured to the 'rail 5| and the ends 52 by the rivets 52', said bars and said flanges 54 being secured together and to a U-shaped weather strip 58 by rivets 59. The joint between upper ends of therplates is identical with theform of side joint just described, the flanges 56 being secured to'short lengthwise extending oppositely disposed angle iron frame bars 50 and weather strip sections 6| by rivets 52, the bars 60 being also suitably secured to the arched bars 51. The end flanges 55, as shown in Fig. 5, rest on the frame member 5| to which they are secured by rivets 63 and the roof is further reinforced at the lower end portions of the side joints by angle iron braces 54 riveted to the side joint construction above described and also to the flanges 55 and the member 5 I. End plates 65 are secured to arched T-bars '56 at the end portions of the roof and have flanges 61 at their lower ends secured to that portion of the rail member 5| at the ends of the car body.

'Ihus with the roof above described when the fastening means yconnecting the roof plates and their frame members with the rail or frame member 5| are removed the entire roof structure for the outer shell may be removed if desired. Also it will be noted that since the parts are riveted together from the outside any one of the plates may be removed from the outside if desired.

From the foregoing description it will be noted that I have provided a double wall structure comprising an inner and an outer shell in which the parts forming the outer shell may be readily replaced without interfering with the inner shell in any way.

Where the car is to be used as a refrigerator car the space between the walls of the inner and outer shells is filled with suitable insulating material. As shown I have provided an inner course 63 and an outercourse 59 ofinsulating material and it will be noted from Fig. 2 that for the sides and vtop these courses preferably are formed by layers of insulating material which extend from one side of the car body to the other over the roof in continuous pieces, a filler layer 10 also being shown interposed between the inner and outer courses over the roof. l

It will be noted that since the space between the inner and outer shells is substantially free of structural framing members, the insulation will 4 not be subjected to undue compression and consequent reduction of its eiliciency. It is also to be noted that the corner spaces have insulating layers 'll and 'l2 mountedtherein.

In order to prevent the condensation of mois- 5 ture upon the outside of the inner metal shell or container and the inner side of the outer shell, these surfaces may be coated with a suitable coating to prevent such'condensation. For example, a coating for this purpose may comprise 10a mixture of cork granules, asphalt and asbestos fibres that `may be painted onto these surfaces, or an insulating material such as hair felt may be cemented directly to the metal surfaces. For supporting the weight of the.insulation `l5 and securing the same in place where necessary it is preferred to cement the inner course 68` to the inside metal shell and the outside course 69 to inside course by means of a suitable moisture proof cement which may be applied in' strips o i 20 spots at required intervals.

It will of course be understood that the metal used for the frame members and the sheathing or plates is steel and that from the foregoing description I have provided an all steel car body 25 having inner and outer shells which form a strong construction and which may be made of `light weight. l

The usual icing compartments formed in the end portions of the car have not been shown as their construction is readily understood by those skilled in this art.

I desire it to be understood that this invention is not to be limited to any particular form 5, or arrangement of parts except in so far as such limitations are included in the appended claims.

What I claim as my invention is; i

l. In a car body, the combination of an yinner 4metallic shell, an outer metallic shell separately 10 supported and spaced from said inner shell at n its sides and roof portions and removable from the exterior of the car body, and layers of insulating material disposed in the space between said shells and extending from side to side over 15 said roof portion and uninterruptedly throughout the length thereof.

2. In a car body, the combination of side plating extending to the corner, reinforcing frame members on opposite sides of said plating at the 20 corner, and end plating secured to said members and said side plating at said corner.

3. In a car body, the combination of side plat ing extending to the corner, reinforcing T-bars on opposite sides of said plating at the corner. l and end plating secured to the base portions of said T-bars at said corner.
